Can't you just type the scale into your print dialogue and have it tile to multiple pages? OS X does it. Failing that, do you have InDesign? It'll do it. Tiling is a pretty standard printing feature. No need to cut up the images into parts.

Thank's, what I actually needed to achieve was to cut the image in 50 images all of them identical in size and with correct side ratio (2:3), then I had to add a border of a very specific width to each side of every cut out image. Then I am sending it for print. I figured how to do it yesterday and had it printed also. It looks great, except the bleed (border) needs to be bigger and I need to find a way to tell the machine operator to not fu*k with my colors and not try to "improve" each photos curve.

You could output a single Photoshop PDF, then use Acrobat to print it on tiled multiple sheets (Print > Page Handling > Page Scaling: Tile All Pages, unless it's changed in the last couple of versions), with cut marks if you wish.

Hello ruhee, welcome to GD SE. Could you please elaborate on your answer to maybe a paragraph, explaining how to use the web service you mention, and then you can even include a link to the service. It's no-follow but your software may be relevant here.
